Member Function Documentation

_SelectorSequence()

Class * _SelectorSequence

(

void

)

The SelectorSequence archetype.

Returns

The SelectorSequence Class.

Definition at line 189 of file SelectorSequence.c.

}

initWithSequence()

SelectorSequence * initWithSequence	(	SelectorSequence *	self,
		const char *	sequence
	)

Initializes this SelectorSequence with the given sequence.

Parameters

self	The SelectorSequence.
sequence	A C-string specifying a sequence of SimpleSelectors.

Returns

The initialized SelectorSequence, or NULL on error.

Definition at line 65 of file SelectorSequence.c.

                                                                                        {

}

matchesView()

_Bool matchesView	(	const SelectorSequence *	self,
		const View *	view

Parameters

self	The SelectorSequence.
view	The View.

Returns

True if all SimpleSelectors in this SelectorSequence match the given View, false otherwise.
